Abstract: A criterion is formulated for the permissible degree of plasmawall-interaction of a thermonuclear plasma. Taking the growth of $\alpha$-particle concentration as a measure, the criterion is expressed in form of a simple relation between few characteristics such as "relative toxicity" and "energy related material yield". The criterionis applied to the example of sputtering by fuel particles in the presence of a cool plasma mantle showing that high-Z materials like tungsten might become advantageous if the "temperature" of the bombarding particles is in the range between 10 and 25 eV.
